The nightmare scenario for Obamacare is a meltdown of the individual health insurance market. If health insurers lose confidence as Republicans struggle with their repeal efforts — or because of the turmoil and price hikes that have already been underway — even more could withdraw, leaving Obamacare customers with nowhere to turn to keep their coverage.
Humana has already done this, raising fears that the meltdown could actually happen. But it's always a vague threat, with no real specifics. Katherine Hempstead and her research team at the Robert Wood Johnson Foundation helped Axios map out the likely impact if other insurers that have been on the fence decide to pull out.
Here's what it would look like: If insurers like Anthem decide to exit the exchanges for 2018, hundreds of thousands of people would be stranded without any available insurers. Some state marketplaces would almost certainly fall apart.
